The name sound cool, but that's all there is to it.
The meaning of the original phrase "Who let the dogs out?" refers to "ugly women" (dogs -> ugly woman, i know, a bit far fetched, but that's what "Baha men" meant with it). :P
So, either "Dutch" in "Who let the Dutch out?" means the opposite (i hope so, at least i am :P) or the same (i doubt :P).
In both ways: it's kind of strange :P
Your original question, i dunno
